Sections with parenthesis in headings rendered twice

[tobiasfranke-ecolytiq]

Describe the bug
When you have some parenthesis in the heading of a description of a tag the whole section gets rendered twice with different font sizes.

Expected behavior
The section should only be rendered once with a consistent font size like the other sections.
